Divide by zeroDo you ever think there would be a second imaginary number? A one about x/0? There could be one, since √1 was once thought to be impossible. #2 20131107 11:01:44
Re: Divide by zeroHi calculator; we can multiply that 3 on both sides and it makes sense. 6 does equal 2 * 3. But since we agree that 0 x anything = 0 let's see what happens. Supposing we say we multiply by 0 on both sides and get the contradictory statement that 6 = n * 0 when we already know that anything times 0 is 0. So, I would say you will never see that definition changed. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #3 20131107 12:43:22
Re: Divide by zeroThose arithmetic are clearly not working with x/0 but that does not stop you from calling it an imaginary number. 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.' 'God exists because Mathematics is consistent, and the devil exists because we cannot prove it' 'Who are you to judge everything?'

Re: Divide by zeroIt is undefined. Imaginary number was a term used for a complex number. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #5 20131119 14:35:44
Re: Divide by zeroI meant, a new kind of a number 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.' 'God exists because Mathematics is consistent, and the devil exists because we cannot prove it' 'Who are you to judge everything?' Alokananda #6 20131119 21:13:24
Re: Divide by zeroIt leads to too many contradictions to call it anything. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
